Chapter:

It was a sunny day in the East Blue, which was normal for the calmest of seas. On one of the island's, called Dawn Island, was an eccentric place, it was actually considerably odd for the safe sea. There, in Fushia Village, lived a boy named Monkey D. Luffy, who had black hair, wide eyes, tan skin, a scar under his left eye, and a large grin on his face. He was walking to a bar, called Party Bar, that he went to quite often and was excited to talk to the pirates that were here for the time being. They were fun to listen to as they told their adventures, and tales about the pirate king. Though, he was kinda annoyed that they wouldn't take him on any adventures or let him join even after he showed them that he was not scared of pain by stabbing himself in the face. Also the captain, Shanks, kept teasing him saying how he was still such a kid. But he wanted to be a pirate so bad!

As he almost made it to the bar, he stopped and looked down at his feet. There, right on the ground, sat an odd looking fruit that was shaped like a large raspberry. It had silver swirls that were outlined in deep crimson and had a stem that was a purple so dark it was almost pitch black. The child picked it up to eat it, but paused as he remembered that Makino, the bar maiden, had told him to always wash off fruit first before he ate it. Sighing glumly at not being able to eat the food, Luffy kept the weird fruit in his grasp as he continued his way to the bar.

When he got there, the small child could already tell that the pirates already were drinking and partying away. Since they paid no attention to him, he went to the back where the sinks were. "Hi Makino!" Luffy greeted loudly as he washed off the mysterious fruit.

"Hello Luffy, what are you doing?" The bar maiden asked.

Luffy smiled brightly at the green haired woman and said, "I found some fruit, and so I'm gonna eat it as a snack before lunch!" When he deemed it clean enough, Luffy made his way to his bar stool and went to eat it. Shanks, the pirate captain of the Red Hair Pirates was next to him and glanced his way for a moment and went back to the conversation he was in with his first mate Benn Beckman. Only for him to pause as his brain finally processed what Luffy had in his hand. Before he could even turn around he heard Luffy gag, "Bluuhhgg! That was disgusting…."

"Hey Anchor, what did you just eat?" Shanks said calmly on the outside while anxiety started to rise internally.

The boy looked at his idol in confusion before replying, "Oh, ah, it was this weird fruit I found! I thought it would be tasty, but it was really nasty!"the boy pouted cutely, though no one would say that out loud, they were pirates after all.

Nervousness starting to show on the Yonko's face, he gulped, "Was this fruit oddly shaped, and did it have swirls on it?"

"Yeah, I found it on the ground on my way here!" Luffy grinned

By now all Shanks could do was smack his hand on his forehead as he groaned in apparent despair. "Luffy, you idiot!" Shanks shouted at the boy and rapping him on the head.

"What? What did I do wrong?" Luffy whined while rubbing his sore head, glaring at the pirate captain.

Sighing Shanks calmed down, then asked Benn to go get him a certain book off the ship. When the man nodded and left, Shanks turned back to the kid, who was pouting at being ignored. "Listen anchor, I'll be frank, I think you ate a Devil Fruit."
"What's a Devil Fruit?" Luffy tilted his head that made him look adorable with the look of confusion on his face.

"A Devil Fruit, is a fruit that gives powers to a person who eats one." At the boy's look of excitement he continued, "Though you can only eat one, for if you eat more than one then you'll die a painful death, and there is also the fact that those with Devil Fruit powers are cursed to never be able to swim again." At this realisation Luffy whined in dismay. By this time Benn had come back giving the book to his captain. Shanks thanked the man and then went back to his explanation, "There are three types of users of the Devil Fruit. First is the most common, which are called Paramecia and it gives the user abilities that can affect their bodies, surroundings, or they can make material. I actually have one with me. It's the Gum-Gum Fruit, which essentially makes the person who eats it body into rubber. After that there is the Zoan types, which allow the user to transform into a creature. Then the rarest is the Logia, which lets the user can turn into an element. To be honest though I think the subcategory for the Zoan types, called Mythical Zoans, can rival the rareness." He smiled as he saw Luffy struggle to comprehend what he was being told, but was slowly understanding. Shanks then gave the book to Luffy, "I want you to look through these and tell me which devil fruit looked like the one you ate."

Luffy nodded before opening the book and began his search. Shanks just sighed and rubbed his weary face. Makino seeing this asked him, "Is it such a big deal if he ate one of these Devil Fruits?"

Shanks looked at the woman, smiling sheepishly, "It's not so much a big deal, it's more of the fact of what the kid's power will be. Some on their own is harmless, but others, if not learned to control, can be very dangerous left alone. Especially logia types! I cannot, in good conscious leave Anchor here if he could be a danger to anybody else." He explained.

Then whatever Makino was going to reply with was cut off as Luffy shouted,"I found it!" Shanks rushed over to the boy and looked at the page he pointed at. His whole crew watched as the color in their captain's face pale considerably. "Shanks are you okay?" Luffy asked nervously.

Shanks once again groaned, "Out of all the ones that you could have found, it had to be a damned Mythical Zoan! Not to mention you found it in East Blue, where it's nearly unheard of to find a Devil Fruit!"

His whole crew gasped, and his sharpshooter, Yasopp, asked, "What zoan is he?"

Looking at his crew he sighed, "He apparently ate the Human-Human Fruit Model: Nephilim. What's worse is that it says that while the last user gave a picture of the fruit, they did not tell its abilities."

Benn looked at the Yonko, "So what are you gonna do, none of us know how to teach a devil user control, especially not a zoan user?"

Shanks frowned in thought, when an idea suddenly came to mind. But before he could share his idea, the doors to the bar busted open, and with it a group of nasty looking men strode in. One of them even announced, "Make way for the Scourge of the Mountain, Higuma!"

The man in question looked around only to sneer at the sight, "So these are pirates, huh?" a tense silence followed as the mountain bandit went up to the bar. "No matter," turning to Makino, he stated, "woman, I need some ale for my men. I think ten barrels will be enough."

"Oh, I'm sorry, but we're fresh out." Makino said nervously.

Higuma scoffed, " So am I supposed to believe that these pirates are drinking water?"

By now Shanks had turned towards the bandit. With a wide sheepish grin he said, "Sorry, it seems that my boys and I ran the place dry. Here you can have this bottle, it's unopened."

The man looked at the red haired captain and made to take the bottle, only to rear his fist back and smashed the bottle, getting the liquor all over Shanks. He then proceeded to speak, "I'm a wanted man, with a bounty on my head….one measly bottle is not enough for a man of my value." Higuma finished gloating, all the while tensions were running high. The whole bar had gone quiet, all the attention now on the pirate captain.

Shank, dripping in alcohol, just sighed, "Look at what you did, now the floor is wet. Makino if you have a rag I'll clean this up." The woman herself went around the bar to help dry off the Yonko just told him to not worry about it.

The ragged mountain bandit grew angry at being ignored and pulled out his sword, before slashing the counter beside the pirate. "If you like cleaning so much, then why don't you clean this?" he growled out as he turned. "Come on, a bar with no liquor and a bunch of pansy pirates is not where I want to be." Higuma scoffed before exiting the building.

The whole place sat in tense silence for a while, when suddenly all the pirates started to hysterically laugh, even Shanks. "Hahahahahahaha, he showed you captain!"one pirate said, and soon everyone of Shanks crew chorused in.

Luffy who had been stewing in anger as the whole finally blew, "What the hell was that?!" All the while he steadily ignored the heated feeling that was growing.

Shanks just gave the kid a smile, "Ah,what's the matter anchor?"

"How can you just let that guy walk over you like that? What happened to you being a great pirate captain? I thought you-aaaahhhhh!" Luffy's tirade was cut off as he shouted in terror when he suddenly was consumed by silver flames. This caused everyone to remember what happened before the mountain bandit came in, and start to panic.

Shanks called out to Luffy, "Anchor! Don't panic, your Devil Fruit abilities are just activating because of your emotions." Luffy hearing this relaxed somewhat, and just waited until the silver flames diminished. What everyone saw had them completely floored and awed. Luffy had changed, and the most noticeable features were the dark purple horns curling out from his forehead, a tail that started where Luffy's tailbone ended , and the silver feathered wings with the tips being the same purple. The people closer could see that the boy had gained claws and had a hint of fangs poking out from under his upper lip. Shanks attention was one Luffy's eyes, though. The iris was a deep crimson and his pupils were black outlined in silver and were slitted like a cats.

By the time everyone had taken in his new appearance Luffy spoke, "I'm kinda tired now…." when he was again consumed by silver flames. When they were gone the boy was normal, and slumped over the counter unconscious. Shanks picked the boy up and handed him to Makino who took him to one of the spare bedrooms above the bar.

Turning to his first mate he told Benn, "Make sure we have enough stocked up to make a three day voyage to the next island and back."

"What's your plan captain?" Benn asked him curiously.

Shanks sighed, "I need to get in contact with an old rival, but I cannot use the Den Den Mushi on a Marine protected island. Also there are some things there we need to get anyways."

"Ah, so you're gonna ask the old man to help?" Benn asked, well rather stated.

Shanks nodded his head, "Like y'all said, we aren't able to deal with something like this. They are and I know that they'll look after him. He'll be in good hands." He then went to Makino and told her that they needed to make a quick voyage, but should be back within the week. After that they left quickly as they wanted to get back as soon as possible.

*Next Island Over*

Shanks had gone ahead of his crew once they had docked. He needed to find a safe place to call the other and older Yonko. As he walked through the open market he paused at one of the jewelry stands, looking at the earrings. He then remembered the only other piece of information about Luffy's ability.

Other Facts: It is unknown why, but it is said that if the user of this Devil Fruit wears anything made of sulfur, it will help control the user's transformation. Rather it makes it so that the user does not transform out of errant emotions.

Shanks zeroed in on a pair that were small dangling ones that had a small golden colored ball at the end. He was gleeful when he left the stand with a pair of sulfuric earrings, and finally went to the safe calling point. He sighed when the den den mushi he was calling finally picked up. "Hello Mar…."

"What do you want Akagami?" the male voice of Whitebeard's first commander grumbled.

"I need to speak to your captain." Shanks stated blunty.

"You can talk to him in person!" Marco growled out clearly irritated.

Shanks just sighed again, "Normally I would, but the….situation is delicate, and…." swallowing his pride he gritted out, "...I need his help. Your help too, now that I think about it."

This had made Marco pause in shock. For the whole time that the phoenix zoan user had been acquainted with the red haired Yonko, he has never asked for help. So he surprisingly went over to his captain. The giant man looked down questioningly at the blond.

"What is it my son?" he asked in concern.

Marco held out the den den mushi saying, "Akagami called, he….asked for help"

Now even more concerned he took the call, "This is Whitebread speaking, what do you want brat?"

Shanks replied quickly, "Listen old man, you know I took a vacation of sorts down in East Blue right. Well, I'm in a bit of bind. The island I'm currently staying at, Dawn Island in the Goa Kingdom, has a place called Fusha Village. There is a boy there that I met, a real interesting one he is, and he unknowingly consumed a Devil Fruit."

"What has this got to do with me?" The giant man grunted.

"The thing is, the Devil Fruit he ate was a Mythical Zoan Fruit. The Human-Human Fruit Model:Nephilim. I can't let the boy stay here with such a dangerous ability with no control, but my crew and I have no knowledge with how to deal with this sort of ability. If it was almost anything else I would have him learn on his own, but he could accidentally hurt the people here if he goes unchecked and untrained." Shanks panted slightly as he finished his small rant.

Newgate hmmmed, before speaking again, "So since one of my sons is has a Devil Fruit ability that is similar, you want me to take the boy in."

"If you do this Whitebeard, I'll owe you. Please, do this!" Shanks said nervously. He knew the man probably would do it anyway, but he had to let them know how important this was.

Whitebeard himself was slightly shocked at the Yonko. He knew how much of a blow to the man's pride that took. This kid obviously meant a lot to the man. "Do not worry brat I'll come get the child. What's his name and is there anyway to contain the boy's abilities till we get there?"

Releasing a breath he didn't know he was holding, Shanks smiled, "His name is Monkey D. Luffy, and yes I have a temporary solution. It should hold until you arrive. Oh, when you do, just go to the Party Bar and ask the woman Makino where the boy is. Tell her that I sent you to get him." and with that the two Yonkos said their goodbyes and ended the call. Shanks smiled in relief and went to gather his crew so they could get back quickly.

*On Moby Dick*

Whitebeard himself chuckled as the call ended looking at his first in command. "My son, it seems that soon we'll have a guest on board and you'll have someone to train."

"What?" Marco asked.

"Go tell your brothers and sisters, we are setting sail to the East Blue!" Whitebeard commanded as he got up to go sit on his throne out on the deck. There was a change in the wind, and he could tell life was going to become real interesting soon.

*With Shanks*

Shanks grinned as he saw the docks of Fusha Village. As they began docking, though, uncertainty began to well up as he did not see anyone at the docks to greet them. Not Makino, not the crazy old mayor, not even little Anchor. His boys, sensing his distress hurried with anchoring the ship, and left with their captain to find out what was wrong. What Shanks did not plan to see was the same ugly ass mountain bandits from the bar in the middle of the street beating little Luffy.

"So this is why no one was at the docks to greet us." Shanks said in a calm manner that suggested slight amusement. It belied the fact that inside his blood began boil as soon as he saw the kid on the ground looking worse for wear.

The kid himself looked at him and yelled, "Shanks!" and he could hear the relief in the boy's voice. The boy then turned to the bandit and yelled, "Let me go you mountain monkey!"

Higuma just sneered and put his sword up near his neck. "Don't you dare move this is between me and the kid. He is the one that started it!"

Shanks did the exact opposite and began walking towards the pair, "You know, I'll let you call me names, throw food at me, hell even spit on me. But I will never forgive you for hurting my friends!" He then had to stop as one of the bandits held a gun up to his head. Looking as calm as ever he said barely above a whisper, "Are willing to bet your lives."

Higuma only had the time to scream "What!" before Benn shot the guy in the head. Higuma paled considerably and stammered out, "That's playing dirty!"

Shanks smirked at this, "Playing dirty? We're pirates what did you expect. A one on one duel?" By now the mountain bandits were pissed.

Higuma yelled out, "Kill them all!" and the other bandits charged, but only got so far as Benn used the butt of his rifle to knock all of them out in one hit. Higuma was shivering by now, and in a fit of terror grabbed the boy under his foot and held him in front of him as a shield and hostage. "You'll never take me!" he shouted before throwing a smoke bomb and running off….with Luffy.

All the pirates coughing because of the smoke were distracted, which means when the smoke cleared Shanks shouted nervously, "Oh no! He took Luffy!" Which led to them splitting up to find the boy.

*With Luffy*

Luffy struggled in the mountain bandit's grasp as the man cackled as he said, "They'll never think to look for a bandit out at sea." He turned his attention from the receding shoreline to the boy in his grasp. "Now what to do with you?" Higuma smirked. By then Luffy could feel the same sensation he got before he transformed, and was trying to hold it back. But it was no use, and he was engulfed by the silver flames again. "Gaaahhh," the captor yelled as he was burned by the flames and subsequently dropped Luffy into the water. As he watched the kid struggle to swim all he said was, "Well, I won't have to deal with you now." before the little dingy he was on started to rock violently back and forth. Turning around Higuma could only gasp as he met his fate as a giant sea king devoured him.

Luffy himself, could on think about how weak he felt in the sea, and now had to worry about the local sea king charging at him. Bracing at the fate that was surely to come he was shocked when and arm wrapped around him pulling him out of the way as the sea king dove out of the water seconds later. Looking up he saw Shanks, who was glaring at the now petrified sea monster.

"Leave." Was the only command the Red Hair pirate captain said, and the monster left frightened. Luffy then started to sob, burying his face into Shanks soaked shirt.

"B-b-but Shanks, your arm!" the scared boy cried bringing attention to the fact that his left arm was now gone.

Shanks was as calm as could be as he replied, not giving anything away about how much pain he was in, "But Luffy it was just an arm, you're more important than that." But Luffy just kept sobbing even as he was still in his zoan form, and as Shanks crew got a boat out to them.

*Later That Week*

Luffy smiled as Shanks nealt down to look him in the eye, "Remember Luffy, keep those earrings in till Whitebeard and his crew get here." Shanks told him.

The boy pouted slightly, "Can't I come with you?"

Shanks looked seriously at him for a moment before he busted out laughing, "Yeah right, like I'd let a kid like you join!"

Getting angry Luffy shouted, "Oh yeah, like I'd ever follow you! One day I'll be the captain of my own pirate crew that'll be better than yours, and I'll become the greatest pirate ever! I'll become the pirate king!" At the end of his rant he was panting out of breath. He was shocked when he felt something being put on his head and reached up to feel a certain strawhat.

Shanks grinned at Luffy as he put his hat on the kid's head, "Then it's a promise. One day when you become a great pirate, you can give this back to me, until then keep it safe for me, as it's my treasure." The boy couldn't help the tears that were running down his face as the Red Hair pirates sailed further and further from the shore line.

A/N: Okay, so I hope ya'll like it so far, I still wanted to keep the ending somewhat the same as Luffy is just not Luffy without his dream of becoming Pirate King.
